MARTIN \VILCOX, OF MIDDLEBURY, OHIO.

IMPROVED STEAM-PUMP.

Specification forming' part oi' Letters Patent No. 31,923, dated April2, 1861. Q

To a/ZZ whom, zit 77mg/ concern: ,K Be it known that I, MARTIN Wrncox,of hliddlebury, in the county of Summit and State of Ohio, have inventednew and useful F is a float which iits looselyinto this cyl! iuder A,and is intended to rise and fall with the water contained in, orreceived into, or discharged from the cylinder A. A rod, R, passesthrough theV center of the float F, having a stop or button, R, at thebottom, and another stop or button, It", near the top. This rod R isconnected to the valve E, which is situated in the upper end of thesteampipe N, which enters the upper end of the receiver A.

H is a steam-pipe which admits steam from the boiler into the pipe N.This pipe II has a governor-valve, J, which is workedl by a iiexiblevalve, M, in the upper head ,of the receiver, whereby the pressure ofsteam in the receiver is kept uniform. This elastic valve M consists ofa circular piece of thin metal or other elastic material carrying anopening through the upper head of the receiver, the circular plate beingupon the inner surface of the head. It follows, therefore, that anincrease or diminution of steam in the receiver will tend to close oropen the valve .I inthe pipe H, and thus secure a uniform pressureindependent of the pressure in the boiler. Around the float, above orbelow, I pack spongeor some other porous substance, as seen at S, forthe purpose of preventing a free mixing ofthe water in the receiver thathas become heated'with the stratum below that is cold.

-B is a discharge-pipe. receiver A stand upon the chamber T.

Both this and the At the upper end ol` this discharge-pipe B is thccondensingchamber O, above which is the valve D,opening upward toprevent the downward flow of water. Apipe, G, connects the steam-chest Ewith the condenser C, so that when the valve E is down the steam canhave a free passage from .the upper part of the re ceiver A through thepipe N to the condenser C. B is a second discharge-pipe which is 'alsoconnected with the water-chamber T.

This pipe is provided with a valve, Q.. for

preventing the return of the water, and is designed to be used for thedischarge of wa ter unmixed with that in the condensing-pipe and chamberO.

O O represent a partition that separates the receiver A anddischarge-pipes from the ingress-pipe I and air-chamber L. This par-`tition is provided with a valve,| I, opening` upward, which prevents allthe water that passes above the partition O O from returning. Theair-chamber` L is to prevent the sudden arrest ol' the flow of waterupward t-hrough the ingress-pipe I when the valve I closed.

This pump is very simple and cheap in construction and is easilyrepaired, working both the expansive and the exhaust powers ot' steam.It is applicable to very light as well as heavy work. and can be appliedwhen other methods could not be economically used, as raising water onplantations in irrigation, and for watering cattle; also for supplyinghotels and private dwellings with water, and

i it does not require the skill of an engineer to run it. Vhen thereceiver A is lled wit-h water, steam is admitted through H and 4N intoA, expelling the water from it through B until F drops upon the buttonIt', which brings down the steam-gate E, closing II and opening G. Thevalve D then closes, andthe water standing higher in B than in A,itseeks a level bypassing down B and up A, trans ferring steam from A intoO, when the steam is immediately condensed, drawing water through pipeI? until it raises F against the i upper button, It, when II is againopened and Gclosed. The uncondensed steam and gas being now collected inC, it is next forced through valve l) and discharged with the water. i

That I claim as my improvement, and desire to secure by Letters Patent,is
